Introduction
Advance decisions to refuse treatment enable people to express their treatment preferences when they may lack mental capacity in the future.1,2 In England and Wales, the Mental Capacity Act specifically sets out provisions governing advance decisions to refuse treatment for people aged 18 or over.1 These decisions are legally binding, if they were made at a time when the patient had mental capacity and they are valid and applicable to the current circumstances.2 In addition, if an advance decision is to apply to life-sustaining treatment, it must be written, signed, witnessed, acknowledge that life is at risk and not have been subsequently withdrawn.2,Reference Huxtable3 In the absence of a valid advance decision, judgments are made on the basis of the patient's best interests.Reference Huxtable3 Where a patient has mental capacity, and is able to communicate their treatment preferences, they can refuse treatment verbally.2 Mental capacity is determined by the ability to understand, use and weigh relevant information, retain that information long enough to make a decision and communicate a decision with others.2
Related terms that have been used in the international literature include advance directives, advance statements and Ulysses contracts. Advance directives refer to treatment choices in the future more generally and advance statements are requests for healthcare treatment wishes or preferences.Reference Huxtable3,Reference Seymour, Gott, Bellamy, Ahmedzai and Clark4 Ulysses contracts are used to mandate treatment procedures if the person loses capacity (for example, treatment choices/preferences when capacity may be lost during psychiatric illnesses such as bipolar affective disorder).Reference Gergel and Owen5 However, the Mental Capacity Act only legally applies to advance decisions to refuse treatment.1 In this paper, we focus on advance decisions to refuse life-saving medical treatment specifically in the context of suicidal behaviour.1–Reference Huxtable3
A recent scrutiny of the Mental Capacity Act in England found low levels of implementation and a lack of awareness and understanding of the Act that may result in clinicians acting in a risk averse way, inhibiting patient autonomy.1,6,Reference Marshall and Sprung7 Previous research indicates a lack of understanding of roles and responsibilities within the Act among clinicians.Reference Dunlop and Sorinmade8–Reference Sorinmade, Strathdee and Wilson11 Clinical and public awareness over the advance decisions component is low.Reference Huxtable3 In the decade since the implementation of the Act, only around 3% of the general population have made an advance decision about medical care choices.Reference Huxtable3,6 Despite the low implementation of the Act, there is an increasing trend in the use of advance decisions and directives in mental healthcare.Reference Campbell and Kisely12 In a recent survey of 554 patients with bipolar disorders, 199 (36.6%) participants were familiar with the Mental Capacity Act, 54 (10%) had an advance decision to refuse treatment and 62 (11%) had an advance statement for treatment wishes.Reference Morriss, Mudigonda, Bartlett, Chopra and Jones13
Advance decisions to refuse life-saving treatment and suicidal behaviour
Despite the legal basis in the Mental Capacity Act, there are likely to be challenges in the use of advance decisions to refuse treatment in the context of suicidal behaviour, and evidence suggests little consistency in patient management.1,Reference David, Hotopf, Moran, Owen, Szmukler and Richardson14–Reference Nowland, Steeg, Quinlivan, Cooper, Huxtable and Hawton16 Legal, ethical and clinical experts have questioned the validity of advance decisions for patients who attempt suicide, particularly in the context of complex psychiatric histories.Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15,Reference Nowland, Steeg, Quinlivan, Cooper, Huxtable and Hawton16 In England and Wales, treatments that are prohibited in an advance decision may be provided under the Mental Health Act 2003 in certain circumstances if the individual is assessed as meeting the criteria for detention.1,Reference Humphreys, Lepper and Nicholson17 However, patients with a psychiatric diagnosis should not be assumed to lack capacity to make such decisions.2
Given that there are approximately 220 000 self-harm presentations to emergency departments annually in England,Reference Hawton, Bergen, Casey, Simkin, Palmer and Cooper18 a greater understanding of advance decisions to refuse treatment following suicidal behaviour is important. There is a scarcity of research examining frequency of advance decisions and suicidal behaviour but one study showed that 2.5% of patients who presented to hospital with self-poisoning and then died had an advance decision in place.Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15 The existing research is predominantly case studies and relates to advance directives in the context of terminal or chronic physical illnesses and/or disabilities.Reference Nowland, Steeg, Quinlivan, Cooper, Huxtable and Hawton16,Reference Houben, Spruit, Groenen, Wouters and Janssen19
Advance decisions to refuse treatment present particular challenges in the context of suicidal behaviour in hospital services but there is limited research in this area. Little is known about how emergency services evaluate advance decisions to refuse treatment and there is evidence from documented cases that ethical, practical and legal difficulties may arise.Reference David, Hotopf, Moran, Owen, Szmukler and Richardson14,Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15
Objectives
The aim of this study was to evaluate the use of advanced decisions to refuse treatment in the context of suicidal behaviour from an emergency service perspective. Our objective was to explore the views of front-line clinicians and people with lived experience on the use of advance decisions in the context of suicidal behaviour. The findings will be useful to inform policy and practice in relation to the feasibility and acceptability of advance decisions to refuse treatment and suicidal behaviour in emergency services.
Method
Design and participants
The study was conducted as part of a large mixed methods and guideline development study on advance decisions, mental capacity and suicidal behaviour. For the focus group component, we used a qualitative pragmatic design, consisting of discussions with paramedic, emergency department and liaison psychiatry clinicians and people with personal experience of self-harm, suicidal behaviour and mental health services. Focus groups were used because group interaction encourages participants to ask questions, share experiences and present points of view on areas of importance to them.Reference Kitzinger20 We were particularly interested in the experience and suggestions of participants.
Recruitment
We used purposive sampling to ensure adequate staff and lived experience group representation. Individuals were eligible to take part in the study if they: (a) were working in clinical services, or (b) had lived experience of psychiatric and/or self-harm services, or (c) were a member of a community support group with experience of mental illness, self-harm and/or advance decisions.
Participants for the clinician focus groups were identified through local collaborators in five participating National Health Service Trusts in North West and South West England. The Trusts were chosen purposively to include a wide geographic and professional range of front-line clinicians and experiences for the focus groups. People with experience of self-harm, mental illness and/or advance decisions were recruited through relevant community groups in two centres. A £20 shopping voucher as compensation for participant's time was made available.
Two experienced researchers L.Q. (chartered psychologist/research associate) and J.C. (nurse/senior research fellow) conducted the focus groups. Participants were informed that all identifiable information would be removed from the transcripts, but that job titles would be included when reporting the findings. Participants were made aware of their right to withdraw from the study before, during and after data collection. Because of the sensitive nature of the discussion the availability of emotional support for participants from line managers and group facilitators, if required, was explained.
Ethics statement
The study was reviewed and approved by the North West- Greater Manchester Research Ethics Committee (REC No: 16/NW/0173) prior to commencement.
Focus group procedure
All participants provided written informed consent for participation and audio recording of the group discussion. We used a structured topic guide with probes to ascertain people's views on advance decisions to refuse treatment and the Mental Capacity Act in the context of suicidal behaviour. The topic guide was developed in line with our research objectives and included the following open-ended questions: (a) ‘What experience have you had of the Mental Capacity Act and advance decisions?’; (b) ‘How do you think the presence of an advance decision which refuses life-saving medical treatment should influence the medical management of patients presenting to hospital with self-harm?’; and (c) ‘Do you think patients who present with serious self-harm and are conscious should be able to refuse life-saving medical treatment?’
Participants were also asked for their opinion on a fictional clinical vignette in order to aid discussions and focus the topic on suicidal behaviour (see Supplementary Appendix 1 available at https://doi.org/10.1192/bjo.2019.42). Fictional vignettes are widely used in qualitative research as a way of discussing sensitive research topics.Reference Barter and Renold21 Vignettes are useful in focus groups with sensitive topics as potential fears or stigma can be situated on to the vignette rather than on to the participants themselves.Reference Schoenberg and Ravdal22
Analysis
Focus group discussions were recorded, transcribed verbatim and analysed in accordance with the thematic framework method,Reference Gale, Heath, Cameron, Rashid and Redwood23,Reference Ritchie and Spencer24 (see Supplementary Appendix 2 for further details). In brief, L.Q. summarised transcripts and wrote notes on non-verbal behaviour and context. Preliminary categories and codes in the coding framework were discussed within the team (R.N., L.Q., S.S. and N.K.) and revised accordingly. The transcripts were then re-read and the framework tested by S.S. and R.N. for two focus groups independently to ensure the codes adequately represented the data. The data were summarised and charted by category and by occupation and lived experience group membership. Emerging themes were refined and revised through discussion between R.N., L.Q. and S.S. Saturation was indicated when no further themes emerged from the charts and/or discussions. QSR International's NVivo 10 Software25 was used for data management and Microsoft Excel for summarising and charting.
Results
A total of 41 participants (28 clinical staff and 13 lived experience group members) took part in one of the six focus groups conducted between June 2016 and January 2017. The focus groups took place either on-site or at the university hosting the research (see Table 1). Each lasted approximately 90 min. No participants declined to take part in the study. Characteristics of focus group participants are displayed in Table 1.

Themes
Three main themes and ten subthemes emerged from the data and are shown in Appendix 1. A brief description of the main themes is provided in Appendix 2.
Participants reported a lack of awareness and anxiety over the management of patients presenting to emergency services with an advance decision to refuse treatment in the context of suicidal behaviour. Several participants had some experience of advance decisions in the context of physical health and end-of-life care. One paramedic had experience of managing two elderly patients with advance decisions in the context of physical illness. The potential for patients to refuse life-saving treatment following suicidal behaviour in a legal document was challenging and the feasibility of the policy was questioned by clinician and lived experience groups.
Theme 1: advance decisions and suicidal behaviour – aid clarity but create uncertainty
Aid clarity and support patient autonomy
The usefulness of advance decisions in the context of suicidal behaviour was viewed as contentious across groups. Some emergency department clinicians and ambulance paramedics saw advance decisions as potentially useful for aiding clarity when understanding a person's wishes and treatment preferences.
‘I think it would provide clarity to the situation because what we often find with incidents involving mental health patients is that they're very complicated and very rarely would we get any clear documentation giving you a clear treatment plan or what to withhold from that patient.’ (Paramedic 4)
Lived experience group members felt that advance decisions could help them have their treatment choices respected when they lacked capacity and could be particularly useful when health advocates or family members were not available to put forward their wishes.
‘…but say, like I've just said, if you've got no family appointee for you, I've always felt there should be some sort of legal propriety there, for somebody to have an appointee no matter what, to have their wishes down, legally.’ (Lived experience group 6)
Legally binding documents
Some healthcare workers viewed advance decisions as legally binding documents that should be adhered to following checks of authenticity and evidence of capacity at the time of writing.
‘…if it was crystal clear and as it was with the advanced decision … I think it would just be followed and respect the patient's wishes, their advanced decision.’ (Paramedic 3)
Emergency department clinicians and ambulance paramedics noted that life-saving treatment may have already commenced before clinicians become aware of an advance decision, for example in self-poisoning incidents that can be reversed with specific medications.
Questioning the appropriateness of advance decisions for suicidal behaviour
In contrast to those clinicians that felt that advance decisions are legally binding documents that should be adhered to, some clinicians were uncertain if advance decisions should be used in the context of suicidal behaviour. Several liaison psychiatry clinicians suggested that advance decisions are more appropriate for end-of-life treatment preferences. Some suggested that suicidal behaviour, suicide ideation and self-harm were symptoms of a psychiatric illness that people could recover from which is different from a terminal physical illness where recovery may not be possible.
‘…if they are terminally ill they're not getting better. If they're depressed, there is treatment and there is the hope that they can get better and that view may be different. Whereas you're terminally ill, there's no going back from this. Depression, there is a way back.’ (Liaison psychiatry clinician 1)
There was a strong view expressed by the liaison psychiatry clinicians that people can change their mind about suicide.
‘To treat or not to treat. This is always difficult as many patients we see who have attempted suicide are relieved that their actions were not fatal. This is backed up by research of survivors. There is no doubt that in many cases the intent “in the moment” is to end their life. Considering this then treatment should be provided. Intent behind the actions would need to be explored, which unfortunately is not always possible.’ (Liaison psychiatry clinician 1)
Lived experience group members echoed this and recalled personal experiences of changing their mind about suicide. One lived experience group member reflected:
‘I did change my mind after I got better, and I was obviously lucky, looking back at it now, I must admit. But at the time, I was very serious.’ (Lived experience group 2).
Participants also queried the desire to die if the person had phoned an ambulance or presented themselves to hospital as this may indicate that they had changed their mind.
‘…it could have been current when she took the overdose but if she then sought help and requested somebody to bring her to hospital, is it then still current? Does that indicate she has changed her mind about her belief, her wishes for this advanced directive, as it would with physical health issues if someone could one minute they said they wouldn't have the treatment they may be kept in hospital and monitored, but they may change their mind the next day.’ (Liaison psychiatry clinician 4)
Mental state and distress fluctuate
Several participants argued that because of the fluctuating nature of mental state/distress advance decisions should not be adhered to without considering the context, including the severity of psychiatric illness, the person's previous medical and mental health history, age and mental state at the time of writing the advance decision and the length of time passed since writing the advance decision.
Participants described the mental state of people in a suicidal crisis as severely distressed, in disarray and focused on attempting suicide. Clinicians indicated that when people attempt suicide, they are not ‘thinking that straightforwardly’ (Emergency department clinician 1), and lived experience group members suggested that when you are in that state you are ‘not in your right mind’ (Lived experience group 2), reflecting on their own personal experiences. The responses from the focus groups indicated that treatment refusal in this context is further complicated by the notion that acute mental distress fluctuates. Mental health was seen as ‘cyclical’ (Emergency department clinician 1) and at different times a person's mental state can be very different; like ‘chalk and cheese’ (Lived experience group 3).
‘I actually know what it's like to hit rock bottom, and I really wouldn't wish that on anybody. And, like, maybe a week later, I might be really low, but I mightn't be as low as I was the week before. But I wouldn't be that far away from it. And so, my thinking would be that little bit different because I'm not at rock bottom, but I'm just a bit up from it. So, therefore, my opinions will be slightly different.’ (Lived experience group 4)
Theme 2: advance decisions with suicidal behaviour – anxiety provoking for clinicians
Professionally and personally challenging
There was anxiety around deciding whether or not to comply with the advance decision in the context of suicidal behaviour. All groups noted a strong feeling of ‘assisting suicide’ if adhering with the advance decision. Community group members acknowledged that it was a ‘horrible’ (Lived experience group 5) and ‘difficult’ (Lived experience group 6) decision for doctors to make. Mental health clinicians echoed this suggesting it was an ‘uncomfortable decision to make’ (Liaison psychiatry clinician 2). There was discussion in all of the clinician groups that anxiety stemmed from feeling that the situation was going against their training and professional role.
‘Yeah, it's very much a step into the unknown isn't it? I think with a decision like this, because the essential ethos of a paramedic is to preserve life and to act with an advanced directive like this, culturally it's very difficult I think for paramedics to take on board, we're better at it than we ever have been don't get me wrong but I still think it's quite a leap of faith.’ (Paramedic 2)
Clinicians also expressed a sense of going against their own personal ethics:
‘from my point of view it's right to do it in the sense that it's legal, but whether it's right to do it from a moral point of view is a bit different.’ (Liaison psychiatry clinician 3)
Anxiety about litigation
Anxiety also stemmed from fears of litigation in this particular context. Some clinicians feared that non-adherence could be seen as ‘assaulting’ the patient (Emergency department clinician 2) and that there was a need to be accountable for your actions.
‘…these would be unusual incidents, these aren't going to be everyday run of the mill decisions, they're not going to happen frequently and there's going to be a degree of scrutiny afterwards and I think that's kind of what we're alluding to and there's the self-scrutiny as in you reflect back on did I make the right decision, have I done the right thing there? Which weighs heavy on some people compared to others.’ (Paramedic 2)
Some emergency department clinicians felt that the decision for medical management ultimately rested with them, that if you are ‘unsure you should treat’ (Emergency department clinician 4) because ‘you're going to get in trouble by standing back and letting people die’ (Emergency department clinician 5). Emergency department clinicians felt that although the guidance is clear, they would ‘struggle with that decision’ (Emergency department clinician 1).
Some clinicians argued that the age of the patient with an advance decision would not affect their care plan, but it would be ‘a really emotive decision’ (Paramedic 5). If a patient was young, concerns were expressed about the duration of mental health difficulties, the transient nature of mental distress over the years and the level of experience necessary in order to make life-ending treatment decisions.
Dissipate anxiety: share the burden of decision-making
Reaching a treatment decision was viewed as a significant responsibility that should be shared with others in order to ease the burden and reduce anxiety. Ambulance paramedics suggested that they would consult with senior colleagues about the decision. Emergency department clinicians indicated that they would consult with senior colleagues, mental health teams and take legal advice. Ambulance paramedics highlighted the need for supervision and emotional support following the decision. However, the logistics of shared decisions were at times not straightforward. For example, mental health clinicians felt they were not always contacted for assessments when patients presented to the hospital with self-harm.
Theme 3: the challenge of validation
Cautious of accepting advance decisions with suicidal behaviour
Clinicians generally refused to accept an advance decision in the context of suicidal behaviour without extensive validation checks. The inability to check mental capacity at the time of writing the advance decision was expressed as a particular concern.
‘And what would make you satisfied that it is if you've never met this person before? You've got the document, were they harassed? I don't know. Well, did they have capacity at the time, a few months ago? I don't know. It says here, who signed it? I don't know. Who was it? Was it a relative? How could you ever be satisfied? (Emergency department clinician 6)
At least in circumstances where the patient was conscious or drifting in and out of consciousness but had an advance decision, there would be an opportunity to assess the current mental capacity of the patient to corroborate the advance decision.
‘I was going to say, if they'd had an advanced directive three or six months ago, and then they're sitting there telling you the same thing, then that increases your belief in them wanting that decision, that being the decision they truly want…’ (Emergency department clinician 4)
Validating advanced decisions in emergency service: practical issues
The groups expressed several practical difficulties when validating an advance decision in an emergency situation. The emergency department clinicians and ambulance paramedics expressed difficulties making verification checks given that mental health crises typically occur outside normal working hours when ‘getting access to someone is incredibly difficult’ (Emergency department clinician 1).
The ambulance paramedics noted difficulty with making a decision at the scene of the incident in the absence of the patient's full details.
‘…we don't have access to the same records, the patient summary care records and I think that can be what throws us into the unknown because we don't know what the patient is that's led up to that point where we're…they've presented to us and we're seeing them. So we're trying to understand very quickly a lot of information about that patient in a very short space of time and very rarely can we get hold of all information to help us make a balanced decision.’ (Paramedic 4)
Participants in the lived experience groups, ambulance paramedics and emergency department clinicians suggested that advance decisions should be registered centrally with the general practitioner or hospital and be available electronically to enable 24 h access for verification. The clinicians preferred the advance decision to be signed by a general practitioner. The lived experience groups felt more confident about clinicians adhering to the advance decision if the patient also had a health advocate or someone with a power of attorney. The lived experience groups, ambulance paramedics and emergency department clinicians all highlighted the need for advance decisions to be clear and detailed, outlining the specific treatments to be given and withheld, to avoid confusion and uncertainty. There was a strong consensus from participants across all groups that advance decisions, including assessment of capacity, should be reviewed regularly to reflect the current views of the patient.
Corroboration from families but with caution
While there was a desire to speak to families for corroboration, both emergency department and liaison psychiatry clinicians were tentative, seeing a need to ‘make sure that they weren't harassed or bullied into signing it’ (Emergency department clinician 6). This was echoed in the community groups, where members gave specific examples of instances where families had ulterior motives; they may ‘want this person out of their lives or may get some money for her passing’ (Lived experience group 6). Lived experience group members felt it was possible that a person in a distressed mental state could sign a document without any consideration of its content.
Discussion
Main findings
Advance decisions to refuse treatment following suicidal behaviour were perceived as having serious ethical, personal, professional and legal implications that limit their acceptability in emergency services. Suicidal intent and mental state were perceived as dynamic and in an emergency setting it was deemed practically impossible to verify the patient's mental capacity at the time of writing the advance decision. Clinicians felt that treatment decisions for patients presenting with advance decisions and suicidal behaviour had increased emotional gravity and professional consequences because a patient with psychiatric difficulties might recover, in contrast to a patient with terminal physical illness. Some participants queried whether advance decisions to refuse treatment were appropriate for use in the context of suicidal behaviour and/or mental health in general.
There were differences between the clinical groups in terms of complying with an advance decision. Emergency department clinicians and ambulance paramedics stressed the legally binding nature of an advance decision and that non-adherence may result in litigation. In contrast, liaison psychiatry clinicians tended to view advance decisions as more appropriate for physical health conditions. All of the clinician groups highlighted difficulties accessing the level of patient information needed to make a treatment decision and would not accept advance decisions without any credibility checks or verification from other professionals. Paramedics did not always have access to full patient records and had to make rapid decisions, so they relied predominately on consulting with senior colleagues. In contrast, emergency department and liaison psychiatry clinicians had stronger relationships with more shared and accessible data about patients.
Issues discussed by clinicians and lived experience group members were largely similar; both highlighted the fluctuating and changing nature of suicidal ideation and raised concerns about the appropriateness of advance decisions in this context. The lived experience groups also expressed the view that advance decisions may offer psychiatric patients the opportunity to have control over their treatment choices and stressed the usefulness of an advance decision when a person does not have a healthcare advocate or power of attorney. A similar expression of patient autonomy came from the paramedics and emergency department clinicians, but focused on the potential for advance decisions to detail patients' treatment choices or existing treatment plans, which could be included in the decision-making process.
Participants in the lived experience groups highlighted the importance of considering the context of the suicide attempt and understanding the person's psychiatric history when making any treatment decisions. In addition to differences between the groups, there were also differences of opinion within both the clinician and community groups; some argued that advance decisions may not be appropriate in the context of suicidal behaviour, whereas others argued that they are legal documents that must be followed.
Comparison with previous research
Previous empirical studies that examined experiences and views of healthcare workers about the Mental Capacity Act demonstrated a lack of knowledge and training among clinicians.Reference Dunlop and Sorinmade8–Reference Sorinmade, Strathdee and Wilson11 In the current study, clinicians were aware of the Mental Capacity Act1 in general but, consistent with the House of Lords report6 and Huxtable,Reference Huxtable3 there was a lack of familiarity with advance decisions and their validity in the context of suicidal behaviour. Similar to research with people who survived serious suicide attempts,Reference Rosen26,Reference Pajonk, Ruchholtz, Waydhas and Schneider-Axmann27 participants highlighted the potential for recovery from severe psychiatric distress and the ambivalence inherent in suicidal behaviour, which raises ethical dilemmas for the use of advance decisions to refuse treatment in this context.
In contrast to previous research, we focused on the advance decisions component of the Mental Capacity Act because of the particular issues that may arise in the context of suicidal behaviour.Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15 Differences between our study and previous research may be because the clinical setting in previous studies have typically examined geriatric and/or end-of-life healthcare, whereas we focused on emergency care.Reference Dunlop and Sorinmade8–Reference Sorinmade, Strathdee and Wilson11
The discussion by clinicians and lived experience group members about suicidal behaviour involving distress and fluctuating thought processes is congruent with research indicating that a person who is suicidal may be in a cognitive state with restricted and limited decision-making capacity.Reference Szanto, de Bruin, Parker, Hallquist, Vanyukov and Dombrovski28 People in this state of suicidal crisis may view their only options as to live or die at that moment.Reference Ellis and Rutherford29 There is also evidence that a person's suicidal intent varies within and between episodes of self-harm.Reference Kapur, Cooper, O'Connor and Hawton30,Reference Kleiman, Turner, Fedor, Beale, Huffman and Nock31 Advance decisions in the context of long-term and sustained suicidal ideation might raise different issues, which would be important to explore in future research.
Strengths and limitations
There is a scarcity of research on the medical management of patients presenting to emergency services with advance decisions to refuse treatment and suicidal behaviour. To our knowledge this is the first study to evaluate the use of advance decisions in this context from the perspective of clinicians and people with lived experience of mental illness and/or self-harm. Our results highlight the challenging and complex nature of clinical care when treating patients who have engaged in suicidal behaviour and refuse treatment with an advance decision. Our findings will be important to inform further research, clinical training, policy and practice in this area. We investigated the feasibility and acceptability of advance decisions following suicidal behaviour in emergency services. It was beyond the scope of our study to explore the significant ethical and moral issue of allowing a person to die from the consequences of a suicidal act but this should be explored in future research.
We recruited front-line clinicians because our research was focused on the evaluation of advance decisions to refuse treatment following suicidal behaviour in emergency settings. Clinical decisions about advance decisions following self-harm for psychiatric in-patients may be different to those for patients who are admitted to emergency services.Reference Cook, Pan, Silverman and Soltys32 The management of advance decisions may also raise separate and further important issues in other settings such as general practice, which necessitates further research.
Our cross-disciplinary approach enabled us to examine experiences, knowledge and views from different clinical perspectives. We also included a broad range of patients and carers with experience of mental health services, mental illness, attempted suicide, self-harm or had lost a significant other to suicide. Future research could more narrowly focus on patients with experiences of attempted suicide to more fully develop themes from this important perspective. There were larger numbers of clinicians than lived experience group members so there is a risk that the clinical stance may have dominated the patient perspectives in the analysis. Future research in this area could use co-design methods to gain a comprehensive evaluation of advance decisions for suicidal behaviour from a patient perspective and recruit a larger sample.Reference Goodyear-Smith, Jackson and Greenhalgh33
We did not recruit any consultant psychiatrists for our liaison psychiatry focus groups, which is a recruitment limitation. Consultant psychiatrists are important to include in research in advance decisions and suicidal behaviour. The expert opinion of consultant psychiatrists is a key determinant in evaluation of capacity and best interests for patients presenting with suicidal behaviour and refusing treatment. Our multidisciplinary team included three senior consultant psychiatrists (J.P., D.L. and N.K.) who were instrumental in the design of the study, interview questions, case study and analyses, which increases the trustworthiness of the findings. However, the views of liaison nurses on advance decisions to refuse treatment were useful to include as they provide the immediate front-line capacity assessments when a person presents to the emergency department with self-harm.34
Although we ensured that context was considered in the analysis by using contextual notes and examining whole transcripts, a weakness of thematic analysis is that a de-contextualisation of speakers' words may occur that may misrepresent the intended meaning. As with all studies involving the use of focus groups, the findings are the result of interaction within the focus groups. Experienced researchers facilitated the focus groups, which minimised the potential for some participants to dominate the discussions. Future research in this area, could use alternative methods such as individual interviews or open-ended anonymous online surveys that may provide richer and more personal data especially from the patient perspective.
Impact on policy and practice
Advance decisions, if developed appropriately and robust hospital policies were in place, could potentially help to clarify complex situations, remove some of the subjectivity involved in the decision-making process and promote patient autonomy. However, the application of advance decisions in the context of suicidal behaviour is fraught with challenges and great care is needed when considering how these decisions should be managed in emergency services.Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15 The Mental Capacity Act in England and Wales acknowledges people should be treated if there is any doubt over the validity of the advance decision. The Mental Health Act can also be used to provide treatment in some cases if there is evidence of a psychiatric disorder warranting hospital detention.34 Clinicians may need additional support when managing patients with an advance decision with suicidal behaviour because of the rarity and gravity of such events. Clinicians may also feel that their professional training to provide life-saving treatment may be challenged.
There is an urgent need for wider discussion around the acceptability and feasibility of advance decisions in the context of suicidal behaviour in hospital services, particularly from the patient perspective. Training to help clinicians recognise a legally valid advance decision and recommendations for the management of advance decisions with suicidal behaviour could help to support clinicians. As these cases are likely to be individual and complex, it may be useful to have evidence-based, legal and ethically informed guidance and training is this area. Given the level of anxiety that clinicians may experience over the use of advance decisions to refuse treatment following self-harm, it is important to ensure adequate support and supervision following such incidents in emergency services.
In conclusion, clinicians questioned the feasibility and acceptability of advance decisions to refuse treatment with suicidal behaviour. In this context, advance decisions were perceived as anxiety provoking and placed additional demands on both professional and personal ethics. Some clinicians stressed the legal implications of non-adherence with patients' advance decisions, but others were uncertain about their appropriateness in the context of suicidal behaviour or mental health generally. Conversely, advance decisions were viewed as having the potential to help people who self-harm gain more self-determination over their treatment in emergency settings.
The application of advance decisions in the context of suicidal behaviour is ethically contentious as patients who might otherwise recover may die from the consequences of a suicidal act.Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15,34 Clinicians should proceed cautiously given the fluctuation of psychiatric distress and suicidal ideation.Reference Kapur, Clements, Bateman, Foëx, Mackway-Jones and Huxtable15 Developing guidelines or clinical recommendations for the management of patients presenting with advance decisions with suicidal behaviour could be helpful in terms of policy and practice and may help to overcome some of the clinical uncertainty and anxiety associated with these situations.
